HERMETIC CLOSURE FOR JARS.

. SPECIFICATION forming part of Letters Patent No. 620,623, dated March7, 1899.

T0 at whom it may concern:

Be it known that I, ALFRED L. WEISSEN- THANNER, of New York, State ofNew York, have invented a new and useful Improvement in Hermetic Olosures for Jars, which improve-- ment is fully set forth in the followingspecification. 1

The object of this invention is to furnish a hermetic closure forpreserve-jars and other vessels of glass, earthenware, or metal in whicharticles of food are put up for the market, the closure being onethatcan be effected expeditiously without machinery of any sort, thatwill securely and hermetically seal the vessel, and that can be easilyremoved and is capable of reuse.

The invention and its advantages will be fully understood from thefollowing description, in which reference is made to the accompanyingdrawings, whereof Figure 1 is a vertical section of the neck of apreserve-jar having the closure attached. Fig. 2 is a plan view of theclamping-ring, and Fig. 3 a perspective thereof.

The closure consists of, first, a lid a, of thin pliable metal, such astin-foil or aluminium, which is placed on top of the jar or vessel;second, a stifier cover B, made of tin-plate or other metal, and, third,a clamping ring, strap, or device 0 for holding the other parts securelyin place.

The cover B has a depending flange which is lined with a ring ofcompressible material I), such as cork or rubber. The cover is placedover the sheet a, of thin metal, pressing it against the rim of thevessel and cansing it to adhere thereto so closely as to make anair-tight joint. This cover is provided on top with one or moreair-holes 7t to permit escape of air from between the sheet a and thecover. It has been found that without these holes the imprisoned airwould form a cushion, preventing the forcing down of the cover to itsproper level. The presence of these airholes is indispensable for coversof small size.

To hold the cover securely in place, which is particularly important inthe case ofvessels containing articles which after being sealed up aresubjected to a sterilizing process, the clamping-strap c or anequivalent device is furnished. In its preferred form, as shown in thedrawings, the strap or ring consists of two parts hinged together by thelink d. At one of the meeting ends is a lug e, while the other has alever or handle f, slotted for the admission of the lug. The latter hasa curved or beveled edge, so that in forcing the lever into place thetwo sides of the ring are clamped tightly against the neck of thebottle. The latter preferably tapers slightly, as shown in Fig. 1. Lug eis perfo rated, and through the perforation is passed a wire g, to whicha lead seal it may be attached, whereby removal of the cover cannot beeffected without destroying the seal.

The thin metal lid a prevents a contact of the inclosed substance withthe compressible lining of the cover. For such substances as do notrequire sterilization or which will not be injured or contaminated bycontact with the lining the lid a may be dispensed with. In this casethe cover must not have any perforations.

Having now fully described my said invention, what I claim is 1. Aclosure for preserving vessels comprising in combination a thin metallid, a cover having a depending flange around its edge lined with acompressible material, a removable clamping device surrounding theflange and engaging a shoulder on the neck of the receptacle for holdingthe cover firmly in place, substantially as described.

2. Aclosure for preserving vessels comprising in combination a thinmetal lid, a flanged cover having the flange lined with compressiblematerial, said cover being provided with one or more air-holes, and aremovable clamp- .ing device surrounding the flange of the cover andholding the latter firmly to the neck of the bottle, substantially asdescribed.

3. The combination with a preserving vessel having a tapering neck, of aclosure comprising a thin metal lid, a flanged cover having the flangelined with compressible material, adapted to engage against saidtapering neck and the clamping-ring, substantially as described.

4. The combination with the preserving vessel, of the flanged coverhaving a lining of compressible material, a clamping-strap In testimonywhereof I have signed this having on one of its meeting ends a lug, andspecification in the presence of two subscrib- 1 0 on the other aslotted lever or handle adapting Witnesses. ed to engage said lug totighten the strap and draw the cover down tightly against the vessel,and a seal or locking device attached by WVitnesses: means of aperforation in said lug, substan- SIDNEY S.
